con'rnmnn HEADER.

Application filed December 3, 1920. Serial No. 428,119.

To all whom it may concern Be it known that I, BEN K. Form, a citizen of the United States, and residing at Oak Park, in the county of Cook and State of Illinois, have invented a new and In]- proved Container Header, of which the following is a specification.

This invention relates to means for attaching sheet metal heads or ends to paper or other fibrous bodies of containers, or cans as they are usually called, and its object is to provide a simple and effective machine of. this character which can be readily and quickly adapted to containers of any desired cross section. v

This invention consists, in combination with rotatable means for supporting the container including a mandrel adapted to fit into the usual depressions in the heads,

of a roller to crimp the edges of the container heads downward and inward, and

means for causing the roller to follow a path which is parallel to the walls of the container, i

This invention further consists in a guide block provided with a guide roove, :1 pair of arms pivoted on the madliine, one of which carries the crimping roller and the other a guide roller which travels in the groove in the guide block, and means for causing angular movement between said arms.

This invention further consists in providing a wedge which is so carried that it may swing with the arms carrying the guide and crimping rollers and be movable between said arms so as to force the crimping roller toward the container.

It also consists in the details'of construction illustratedin the accompanying drawings and particularly pointed out in the claims. r

In the drawings, Fig. 1 is a side elevation and Fig. 2 is a front elevation of this improved container header. Figs. 3 and 4 are sections on the lines 3'3 and 4-4: of Fig. 1 respectively. Fig. 5 is a section on the line 5-5 of Fig.3. .Fig. 6 is a side elevation of the crimping arm and the guide mechanism therefor. Fig. 7 isv a section of a portion of a contalner showing the manner of attaching the top.

Similar reference characters fefer to like parts throughout the several views.

The 'machine shown in the drawings is mounted on a base 1 supported by legs 2 and the pedestal 3.having upwardly ex tending arms 4 and 5 which supportbearings for the main shaft'6. On one end of this shaft is a gear 7 meshing with thegear S on the spindle 9, journaled in the bearings 10 and. 11. On the lower end of this hearing 11 is the guide block 12 and the mandrel 13 is the lower end of the spindle. Adjustably mounted on the pedestal is a guide bracket 14 for the vertically mounted post 15 which carries collars 16 to limit the upward movement of the post and to receive the thrust of the spring 17 which receives this thrust from the slidable collar 18 mounted in the forked front end of the lever 19. The post 15 has a central hole to receive the stem 20 which may rest on a ball 21., A table 22 to support the container bodies is attached to the upper end of the stem 20 and rotates with the containers as they are turned by the spindle 9 and the mandrel 13.

Any desired clutch drive may be employed to rotate the shaft 6. I have shown the pulle 25 rotatable on the shaft and it may be riven in any desired manner and is constructed to fit the clutch cone 26 which is slidable on the shaft and connected thereto by a feather 27. A pin 29 is centrally mounted in this shaft and engages the' cross pin 28 which is mounted in a slot in the shaft so that when this pin is forced forward, the cone 26 is forced into the pulley 25 to cause this pulley to drive the shaft.

The foot pedal 31 mounted on the rod 32 carries. a pin 33 on which the link 3i is mounted. This link connects to the lever 19 and to the second link 85, which, in turn, connects to the vertically slidable bar 36 guided by the arms 4;, and 37. These parts are normally held up by the spring 38. On the bar 36 is mounted a cam block 39 which engages the pin 29 and forces it inward sufficiently to cause engagement of the clutch when the pedal 31 is depressed. The block 39 is long to permit completion of the movement of the other parts connected to the pedal. Any other desired means to drive the shaft 6 may be employed.

The mandrel 13 is provided with a plate 41 at its lower end which fits within the head of the container, the head 42 being usually formed with. an upstanding and then laterally. projecting flange 43, as shown in Fig. 7, and the object of this machine is to turn the outer edge of the flange in against. the body 44: of the container. As the mandrel isrotated, the container 44 and the small table 22 rotate with it.

The shape of the plate 4C1 on the lower end of the mandrel is that of the cross section of the container 1 1-, but it is a trifle smaller to allow for the thickness of the metal of the head. The fian e 4:3 is curled over by roller 46 of well known form mo'unte'don a pin 47 on the arm 48, which ali llis mounted on a vertical shaft 4-9 (Fig. 3) carried by the arms 50 and 51 that extend from, the pedestal 3. See Fig, 6.

A; second arm 53 is also mounted on this shaft and carries a pin 54 on which theguide roller 55 is mounted, and this roller extends up into the groove 56 in the guide block 12, which groove is of such a form that the pin 5e travels in a path which is substantially a reproduction of the periphery of the curledover edge of the container head shown in Fig. 7. This cam groove may be of any desired form, depending on the cross section of thecontainer body to be headed, which may have any number of sides or be of any desired cross section. The two arms 4. and 53 are drawn toward each other by the spring 58.

' A third arm 59 is mounted on this vertical shaft 49 and in its free end is slidable astem 60 which is normally held up by the spring 62. On this stem is a wedge 63 adapted to extend down between the arms 18 and 53 as shown in Fig, 5, the lower arm havinga lug 6 4; to give abearing to the wedge in alinement with the upper arm.. A hook 65, a thin flexible strap 66, a clamp 67 and a screw-threaded rod- 68 slidable in the pin 33 and threaded into the clamp 67 constitute the connection between this wedge and the pedal 31.

' The operation of this mechanism is as follows: When the pedal 31 is released it is elevated by the spring 38 which lifts the cam block 39 out of engagement with the pin 29 and thus permits the clutch to disengage. At thesame time the post 15 slides down and with it the table 22 and the container, which may then be removed and be replaced with another, on the upper end of which a head 12 has been placed. The pedal 31 is then depressed, which causes the table 22 and the container to be elevated and the head 12 to be pressed against the mandrel, the plate 41 fitting down in the depression with in the flange 43 of the container head. Continued movement of the pedal compresses the spring 17'and also moves down the cam block 39, which causes the pedal 9 and the mandrel 13 together with the container and the supporting table 22, to rotate.

At this time the pin 33 engages the head 7 0 of the screw 68 and pulls downthe flexible strap 66, which causes the wedge 63 to force the arm 48 and the crimping roller 46 against. the laterally projecting flange 13 of the container head. With the exception of provided with a cam groove 56 adapted for containers. which are rectangular 'in cross section, but this guide block maybe replacedby others with any desiredcam grooves so that the maclnne may be adapted for containers of any desired cross section and size by merely substituting new plates 41 and guide blocks 12.

The details of the operating and driving mechanism and the proportions of the parts may allb'e' changed-bythose skilledin the art without departing from the spiritof my invention as set'fjorth in the following claims.
